Green Tree Frogs Survive by Getting Water Through Condensation

Australian green tree frogs live in the dry desert without dehydrating. This has been a mystery - until now. They move from a cool night into warm burrows. Then they "mist-up". They sit in the cold air for hours until they can hardly move. There is a good reason for this.

It has been discovered that their skin "takes-on" water. Inside the burrows water is in the air due to the warmth. Droplets form on their cold skin by condensation. A group of tree frogs frequented a hollow tree in the dry outback. Researchers caught some frogs, cooled them in the cold night air, lowered them into the log in a cage for a quarter of an hour, Then tested them. The frogs gained 0.4 grams in weight, their bodies glistening with water droplets.

It is now believed that lizards and spiders also use this technique to get water. Earlier work in the laboratory indicates this. Just a little water is enough to survive.

Anthropology Has New Theory on Australian Aboriginals

New theory on Australian Aboriginals - Anthropology. Australian Aboriginals split from Eurasians and moved south into the dry continent. Twenty thousand years later the world warmed up and Australia was cut off from its northern neighbors. This is the latest theory.  But when Europeans initially came to Queensland there were two types of native people. Each was a distinct genetic pool. One was like Papua New Guineans. The other was very slight and shorter. It is the latter that predominates today. Papua New Guineans Australian Aboriginals Some scientists still hold that there was only one move out of Africa. This is an unsustainable supposition. The doors for movement were always open. Australian Aboriginals were quite unique. It seems that they were the first to leave Africa. There is also the question of Tasmanian Aboriginals who were wiped out by arriving Europeans. There is no evidence of them now. They could not light fires. The flames had to be stolen f

Beatboxing - Percussion Sounds of the Mouth

There must be a dearth of things to study. Scientists are now researching the odd sounds that people make. It may seem weird but its true. Those who can make odd sounds are called beatboxers. Scientists are interested in percussion sounds. These are expressed in Celtic, Chinese, North American and Indian cultures. Hip-hop is an area of great interest. A young "practitioner" had MRI scans done on his mouth while he created percussion sounds. The conclusion reached is that a lot of brainpower is involved in imitating percussion. It "is a small part of the larger puzzle," experts say. In my view it takes little mental concentration. Just put your tongue behind you top teeth a "tap" away. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml http://www.technorati.com/blogs/ . . . . . . . . . . . . . . . . . . . .
